| Abstract: | A large deformation and elastic-plastic analysis for solid rocket motor with locking ring struction is presented in the paper. The material of composite case is considered as orthotropic axi-symmetric one and the contacted problem of three bodies is solved by using point-point gap element. Based on the above analysis a set of testing advice was designed and the water pressure test done. Finally, the calculating results and result analysis are presented. |
